Definitions

  • the present invention relates to a deck of ships comprising an apparatus for gripping and raising, orienting and transporting helicopters of the wheeled type, in particular on board ships, platforms and the like.
  • EP 0,518,405 also discloses in the name of the same Applicant an apparatus for gripping, handling and transporting helicopters in particular on board platform ships and the like, which comprises a pair of gripping elements arranged parallel to the longitudinal axis of the ship and designed to translate transversely with respect to said axis, in engagement with corresponding transverse guiding means fixed to the deck, and to assume an inclined, but mutually parallel position with respect to said guiding means, under the action of mutually independent operating means.
  • Said apparatus which enables the helicopter to be brought into the correct position for subsequent coupling to the carriage for longitudinal transportation towards the hangar, is particularly versatile and suitable for use with both helicopters of the runner type and helicopters of the wheeled type, but has complex mechanisms, operating devices and associated control devices which also require additional modifications to be made to the structure of the ship for example in order to fit the transverse guides.
  • the technical problem which is posed, therefore, is that of providing a simple and reliable apparatus suitable for hitching and raising a helicopter of the wheeled type in order to transport it, from any position inside a well-defined landing area on the deck of a ship, into a position where it is correctly oriented and aligned with respect to longitudinal guides provided on the deck of the ship itself for subsequent transportation towards the hangar, whereby such an operation must be able to be carried out easily and repeated whatever the relative position of the helicopter, inside the landing area and with respect to the longitudinal axis of the ship.
  • This operation must also be able to be carried out automatically, and/or manually, but without operating personnel present on the deck in the vicinity of the landing zone, and allow the apparatus itself to be kept under cover inside the hangar until the moment when it is actually used for recovery of the helicopter.
  • the helicopter may be in any position with its longitudinal axis Y-Y at angle to the longitudinal axis X-X of the ship, with which it must therefore be aligned for subsequent translation inside the hangar 3.
  • the deck la is provided with longitudinal rails 4 extending from inside the hangar as far as said grid 1b; as illustrated in the cross-sections shown in Figures 2 and 3, said rails 4 each have engaged with them two anti-tilting travel units 5a and 5b respectively secured to the opposite ends of two bars 6 arranged parallel to the longitudinal axis of the ship.
  • the travel units 5a are directly connected to the rear end of the bar 6, while the travel units 5b are connected to the front end of the bars 6 via a hydraulic cylinder 5c arranged between them.
  • Said travel units 5a, 5b haves suitable wheels 5d for travelling on the deck 1a, as well as anti-tilting wheels 5e ( Figure 3) and wheels 5f for transverse locking.
  • the movement of the bars 6 in the longitudinal direction is performed using means which are known and therefore neither illustrated nor described.
  • the beams 9 are in turn hollow and only one of the two beams has inside it a bolt 10 which can be translated in either direction via a double-acting cylinder 10a.
  • both the beams 9 have, on their external surface with respect to the carriage, parts (known per se and not illustrated) for supporting and guiding a cursor 11, movable parallel to the beam 9, from which there extends an arm 12 carrying the devices 13 for gripping the helicopter 2, described below.
  • Only one of the cursors 11 also carries a bar 11a which is also parallel to the beam 9 and designed to be inserted into a corresponding seat llb of the other cursor 11 (Fig. 7) provided with suitable means for locking the bar itself.
  • the device 13 for gripping the helicopter 2 is designed to effect coupling with the head 2e of a pin 2d projecting from the inner side of the carriage shank 2c supporting the hub 2b of the main wheel 2a of the helicopter 2.
  • the gripping device consists of a flat plate 13a provided with a bottom shoulder 13b projecting horizontally towards the wheel 2a; the wall 13a has mounted on it two jaws 13c slidable in the horizontal direction and designed, upon operation of hydraulic cylinders (not shown), to close around the head 2e of the pin 2d so as to retain it in the transverse and longitudinal direction.
  • the seat 13d of the plate 13a also houses a nose-piece 13e which is kept normally pushed outwards by a spring 13f and can be retracted inside the seat by operation of a hydraulic cylinder (not shown).
  • the apparatus operates as follows:
  • the arms 6 carrying the beams 9 are moved outwards, the latter during this phase being rotated in the open position parallel to the arms 6 themselves.
  • the two longitudinal arms 6 are brought into a position underneath the helicopter between the front wheel 2p and main wheels 2a since the open beams are able to freely pass by the obstacles represented by the front wheel itself and the radar housing which, if present, projects underneath the fuselage of the helicopter 2.
  • the beams 9 are rotated through 90° into the closed position and the cylinder 10a operated so as to cause the bolt 10 to emerge from one of the two beams 11 until it is inserted inside the other facing beam 11.
  • the two beams 9 form an assembly which is highly resistant to flexing both in the vertical plane and in the horizontal plane, but are at the same time free to slide with respect to one another in the longitudinal direction and in the two directions away from and/or towards each other, as will become clearer below.
  • the apparatus forms a single articulated structure and the two bars 6 are moved in the direction of the wheels 2a of the helicopter asymmetrically so as to obtain alignment of the arms 9 with the axis of the wheels themselves ( Figure 6), the inevitable increase in the distance between the pins 9a being compensated by sliding of the hollow beam 9 on the bolt 10.
  • the two cursors 11 are operated so as to move away from each other until they bring the gripping devices 13 into contact with the head 2e of the pin 2d of the wheel 2a, the manoeuvring mechanism exerting during this phase a light pushing action without forcing the wheels of the helicopter; in this position the cursors 11 are locked together by means of the bar 11a so as to form a single rigid element able to withstand the transverse forces transmitted by the helicopter once the latter is raised.
  • the head 2e of the pin 2d rests on the wall 13a of the gripping device 13, but may be displaced with respect to the central position owing to the imprecise positioning of the beams 9 with respect to the wheels 2a.
  • the head of the pin may move a certain amount in both the horizontal and the vertical direction, while remaining within an area corresponding to the flat plate 13a.
  • the vertical jaws 13c are symmetrically closed towards the centre so as to lock the head 2e and prevent both the longitudinal movements and outwards displacement of the helicopter wheels.
  • the first of these operations consists in moving the arms 6 in opposite directions, causing rotation of the beams 9, and hence of the helicopter, so as to bring its axis Y-Y parallel to the longitudinal axis X-X of the ship.
  • the front wheel 2p of the helicopter is rotated through 90° with respect to the axis Y-Y of the helicopter.
  • the cursors 11 (which are fastened together) are translated in the transverse direction so as to cause the axis Y-Y of the helicopter to coincide substantially with the axis X-X of the ship.
  • Figures 9, 10 and 11 illustrate a variation of an example of embodiment of the apparatus according to the invention.
  • the arms 6 may be connected in the transverse direction by an arm 6a at the end opposite to that of the helicopter, thus forming a carriage 106 substantially consisting of a U-shaped frame, the parallel fixed arms 6 of which are arranged parallel to the axis X-X of the ship and are internally hollow so as to contain a beam 7, the end 7a of which inside the arm 6 is fixed to the rod 8a of a cylinder 8 which is actuated so as to cause the beams 7 to emerge from and/or retract into the arm 6.
  • the said cylinders 8 are of the double-acting type and may be actuated so as to cause equal displacement of the two beams 7 in opposite directions.
  • the free end 7b of the beams 7, on the other hand, is supported by the travel units 5b already described and rotationally connected to the bar 9 via the pins 9a as in the case above.
  • the carriage 106 which is arranged in its configuration with the beams 9 rotated into the open position parallel to the arms 6 and the sliding beams 7 in the central position, can be brought into a position, underneath the helicopter, located between the front wheel 2p and the main wheels 2a since the open beams are able to freely pass by the obstacles represented by the front wheel itself and the radar housing which projects underneath the cockpit of the helicopter 2.
  • the helicopter is engaged by the gripping devices 13, following which the movement of the beams 7 in opposite directions inside the fixed arms 6 of the carriage 106 causes rotation of the helicopter 2, which is arranged parallel to the longitudinal axis X-X of the ship.
  • the axis Y-Y of the helicopter is made to coincide with the axis X-X of the ship and in this position it is possible to bring the front wheel 2p into the centre of a device 20 for raising the same, integral with the transverse arm 6a of the carriage 5. In this way the helicopter is fully secured to the carriage 5 and can be transported by the latter into the hangar.
  • the rotating beams 9 can be arranged inside the arms 6 instead of outside them; or the cursors 11 can be arranged on the inner side of the rotating beams so that the main wheels are able to travel past and the helicopter can be gripped with a return movement towards the wheels themselves.
